14 Mainstreet Equipment
User Manual
Undercounter (541HTUC30):
Required water dynamic pressure measured at pressure gauge 20psi ± 5psi.
CAUTION: Do not confuse static pressure with ow pressure. Static pressure is the line pressure in a“no
ow” condition (all valves and services are closed). Flow pressure is the pressure in the ll line when
the solenoid valve is opened during the lling or cycle.
In areas where the pressure uctuates or it is higher than the recommended pressure, a water pressure
regulator shall be installed between the shut-o cock and the water hose (Fig. 1.).
If the water pressure is less than required, installation of a water pump is required.
The hot water heater should be set to deliver 140 ºF (not lower than 122 ºF) water temperature to the
dishwasher for best results.
Slowly turn on the water supply to the machine after the incoming ll line and the drain line have been
installed. Check for any leaks and repair as required. All leaks must be repaired prior to placing the machine in
operation.
The following requirements are necessary for the correct hydraulic installation of the machine.
• The hydraulic circuit must be tted with a valve to shut-o the water supply.
• Check that the mains pressure is within the range indicated.
• To optimize the work of the machine, the water temperature at the machine intake should be within
the following range: 122 ºF (50 ºC) < Hot water Temp < 140 ºF (60 ºC)
• If using hot water, the water temperature must not exceed 60 ºC / 140 ºF.
• All the machines should have a 3/4”screw-on connection.
8.5 Drainage connection
Attach the drain hose as shown in Fig. 2 (on next page). The drainage pipe must always be tted on a siphon
to prevent the return of odours.
All piping from the machine to the drain must be a minimum 1-1/2” I.P.S. There should also be an air gap
between the machine drain line and the drain. For natural overow eciency use oor drain.
The water draining from the machine must ow freely and therefore the drainage pipe should be lower than
the drainage outlet (Fig. 2).
If the drainage pipe is not lower, a drainage pump will be required. This must not be mounted at a height of
more than 19 3/4” for undercounter dishwashers (Fig. 3). In this case, the pump may be requested at the time
of purchase or subsequently.

User Manual
9.1.2.1 Filling and heating
In the Undercounter model, when the machine is switched on, it will start to ll the
machine. First the rinse boiler is lled and then the wash tub. The lling process may last
a few minutes. Once the wash tub is full, the boiler and the tub start to heat up. Although
it is possible to start the wash process, this is not recommended as the water inside the
machine is not yet at the ideal temperature. When the machine has reached the ideal
temperature for washing the dishes properly, a light comes on, advising the user that
the machine is ready. The required temperature of the machine is over 180 ºF in the rinse
boiler (see thermo-stop chapter) and over 158 ºF in the wash tub. It is recommended that
the water in the dishwasher is changed every 40/50 washes or twice a day.
The door must be closed for the machine to start lling. For safety reasons, if the
door is open, the machine will not ll.
The machine you have purchased has a safety thermostat in the boiler and another for
the tub, so that in the event of the breakdown of any of the main thermostats, the safety
thermostats switch o the corresponding heating.
During the rst heating of the day, the boiler may reach a higher temperature
than that mentioned above due to heating inertia. This is normal. If pressurized
steam is observed coming out of the rinse arm nozzles, while the boiler is
heating, the technical service should be notied.
9.1.3 Hygiene practices
• Operators must strictly observe all hygiene requirements when handling clean dishes
and cutlery.
• Do not touch clean dishes with dirty or greasy hands. Handle the dishes/cutlery with gloves or
clean hands to prevent contamination. Be careful as the dishes will be hot.
• Use clean sterilized cloths to thoroughly dry the dishes. Do not dry the plates with
kitchen towels or cloths that are not sterile.
• Wait until the machine reaches the correct wash temperature to ensure a thorough
disinfection and wash. To obtain optimum results wash the dishes when the machine is ready.
• Drain the wash tub and rinse the lters at least twice a day or every 40-50 wash cycles.
• Make sure that the quantities of detergent and rinse aid dispensed are correct (as
recommended by supplier). At the start of the work day, check that the quantity of
product in the reservoirs is enough for the daily requirement.
• The dishwasher should be kept perfectly clean and maintained.

20 Mainstreet Equipment
User Manual
9.1.4 Preparation of the dishes
Before washing the dishes, the preparatory steps below should be followed:
• Remove the largest pieces of waste from the dishes before placing them in the baskets to
avoid blocking the lters, nozzles and tubes.
• Wash glassware rst.
• Put the plates in the rack basket.
• Place the glasses upside down.
• Place the cutlery in the cutlery baskets with the handles downwards. The dierent pieces of
cutlery can be mixed.
• Place the cutlery baskets in the lower baskets.
9.1.5 Selecting the wash cycle
Before starting the wash cycle, place the corresponding basket containing the dishes in the
machine and close the hood/door.
Before starting the wash cycle, the machine should have the ideal temperature for washing
the dishes properly, indicated by the temperature on thermometers, advising the user that the
machine is ready. The required temperature of the machine is over 180 ºF (see thermo-stop
chapter) in the rinse boiler and over 158 ºF in the wash tub.
In undercounter dishwasher, to start the wash cycle, a wash cycle button must be pressed (P1)
with the door closed.
When the wash cycle starts, the selected program led will switch on blinking.
The door must be closed for the machine to start the wash cycle. For safety
reasons, if the door is open, the wash cycle will not start.
If you start your dishwasher prior to your boiler reaching a minimum of
180ºF (83 ºC), YOU WILL HAVE AN EXTENDED WASH CYCLE!
